Fig. 4: Gross morphological observation of colon tissue in the treatment group and control group at 12 weeks after BAC treatment.
From: Establishment and identification of an animal model of Hirschsprung disease in suckling mice
a, b Fecal accumulation was obvious in the distal colon of the treatment group, forming an expanded colon with irregular shape and uneven thickness. c, d The size of the distal colon of the control group was uniform and smooth, without obvious fecal accumulation. e The length of the colon was found to be shorter in the treatment group than in the control group.
